The Silverstone Heligon HE02 is being sold as a passive heatsink for sub-95W TDP processors, so today on Frostytech we'll put this big, boxy, silent heatsink through its passive paces. No fans will be used in the testing, just good old noise-less convection cooling. We should note that wire fan clips are supplied for users who wish to add two 120mm fans. Given the Heligon HE02 heatsink stands 151mm tall and has a footprint of 170mm x 130mm, adding 50mm of width onto that 130mm wide frame is inevitably going to be a challenge for most motherboards... Never the less, the option exists.
